To all whom it may concern: v

Be it lrnowntha't I, DAVID J. NELsoN, a

'- citizen, of the United States, residing at the provision of a structure in which leakage of, rain water, melted snow and the like will be prevented even though a heavy wind should blow the rain.

It is well known that in the ordinary con struction if the win'd'is blowing severely the V water backs up and overflows the flashing at flashing member,

' the top of the window, a fact which results in leakage and consequent damage to the interior of the building. It is withthese facts in' view that I have designed the present structure which has a peculiar arrangement of flashing which will positively exclude water under even the most trying circumstances, the device being furthermore simple and inexpensive in manufacture, easy to install, efficient and durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illus-, trated in the accompanying drawings, in which:

Figure l is a plan view of my window mounted in a roof,

Figure 2 is a vertical section taken through the roof and looking at the outside of the device,

Figure 3 is a vertical section through the window,

Figure 4 is a fragmentary perspective view of parts of the frame prior to assembly,

Figure 5 is a perspective View of a detail element,

Figure 6 is a Figure 7 is a perspective view of one binding member.

Referring more particularly to the drawings the letter A designates a roof having a window opening therein.

In carrying out my invention I provide a rectangular frame 10 of a size and shape to fit over the window opening and this frame perspective view of oneis constructed of sheet metal such as gala vanized iron or the like. I cludes a top ll, bottom 12-and sides 13, all of which extend at right angles to the surface in which the window opening is lo-' This frame in-.

cated. Formed on the top member 11 is a right angularly extending flange'14 while similarly on the lower member or bottom 12 is a similar flange 15.

Formed onithe top member 11 of the frame is a strip 16'which extends the full width of the frame and which is of rightangular.

shape to define a flange 17 lying on the roof above'the window opening. r

The device is placed in :position by placa ing the frame 10 on the sheathing of the roof construction at the window opening, the flange 17 lying on the sheathing at the'top of the opening and. serving to temporarily support the structure. A window 'paneni's designated at P and is arranged in the frame as shown in Figure 1.

The shingles or roofing strips B are then applied to the roof in overlapping relation in the customary manner, the row of shin gles at the top of the window overlying the flange 14. The flange 15 at the bottom of the frame overlies the shingles which are immediately below the window opening and passing through the flange 15 is any desired number of securing members 18 which serve to anchor the lower end or bottom of the frame.

Located outwardly of the sides 13 of my frame are right angular pieces of flashing 19, the lower one of which overlaps the projecting corners of the flange 15 and the uppermost one of which underlaps a flashing member 20 at each upper corner of the frame. The intermediate flashing members 19 overlap one another successively in exactly the same manner as shingles and the shingles are of course laid in place together with these flashing members 19, the shingles and flashing members being applied together as clearly shown in Figure 2. It is of course apparent that at the upper corners of the device the shingles overlap the flashing member 20 in exactly the same manner as the members 19 are overlapped.

If desired or necessary, the additional flashing element 22 disclosed in Figure 5 may be used at each of the corners of the frame. However, these elements are not shown as being in place in any of the figures inasmuch as they may be considered as merely optional additions or attachments.

After all the flashing members 10 are placed in position and the shingles likewise laid, I apply to the sides 13 ot' the frame, channel shaped binding strips 21 which ongage against inside of the frame and against the outside oi the Flashing members 19 and 20 for holding all the parts rigidly in position and for making a finished appearance. These channel shaped members 21 also serve to hold the pane P in position within the frame. Obviously the fran'ie thus formed is capable of hold a sash or frame F carrying a pane oi glass G.

In the use of the window it is of: course apparent that it will be impossible for water to seep in at any point owing to the elaborate system ol (lashing which co-acts with the shingles. As the flange 14: extends upwardly an appreciable distance below the shingles above the widow it is apparent that water cannot back up and escape beyond the upper edge of the flange til-i At all other points there is an overlap which will positivoly prevent seepage even though a high wind may be blowing.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and consequently inexpensive and easily mounted window construction which will be weather proof under any and all circumstances and which will thus be a distinct improvement over existing structures of this character.

\Vhile I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form. construction and arrangement ot parts as will not depart from the spirit oi the invention or the scope ol the subjoincd claim.

Having thus described my invention I claim:

In a root window frame construction, a rectangular lrame including similar side members and top and bottom members onnected therewith the top member being formed from a single sheet ot resilient material cut transversely near its ends and bent longitudinally between the cut and rebcnt' to define an upstanding inverted channel portion, the ends being bent laterally and being formed with extensions extending at right angles to the laterally bent ends, the bottom member being s milarly 'lormcd lrom a single sheet of resilient material cut transversely near its ends and bent longitudinally between said cuts and rcbcnt to dctinc an upstanding inverted channel shaped portion, the sheet, of the top member being adaptcd for disposition beneath the shiilil'lcs at the top of the window opening and thc sheet of the bottom member being adapted for disposition upon the top ot the shingles. at the bottom of the window opcning. thc sides ot the frame each being formed From a single sheet of material bent into channel shape corresponding to the channel shapcd portions of the top and bottom members and terminating in right angularly extending tongues received slidably within the first and second named channel members.

In testimony whereof I atiix my signature.

DAVID J. NELSON.
